Type: Feature request
NLog.Config version : 4.2.3
Platform: .Net 4.6.1
includeTimestamp not present in NLog.config. Also, it cannot be accessed, i.e, it gives error.

That's a bug
We should include it here:
Thanks for reporting!
This will be fixed in 4.3. It has been renamed to internalLogIncludeTimestamp (for consistency)
